The Swedish cartoonist Lars Felix, who has lived under police protection since 2007, died Sunday in a car accident, after receiving death threats for his satirical cartoons of the Prophet Muhammad. The 75-year-old painter was killed along with two policemen who were with him after their cars collided with a truck, Swedish police confirmed. "The accident is being investigated like any other traffic accident," a police spokesman told AFP. But because it is also related to the killing of two policemen, a special section of the Public Prosecutor’s Office has been assigned to this investigation.” The accident occurred near the small town of Markarid when the car in which Felix was traveling collided with a truck, both vehicles caught on fire, but the truck driver was rescued, who is now undergoing treatment in hospital, police said. A police statement indicated that the cause of the accident was not clear. "The person we were protecting died along with two policemen," said regional police chief Karina Pearson. Felix has been under police protection since one of his 2007 caricatures of the Prophet Muhammad outraged Muslims.

In 2015, Felix survived a shooting incident during a conference in Copenhagen that killed a Danish director
